v0.38.0
Isomorphic plan reuse (scenario like): a scenario can reuse another's already-proven cached plan instead of an LLM planning call — Windup instantiates it for this scenario's route/values, then executes + verifies before trusting it, falling back to LLM planning on any mismatch (never a silent false green). On success llm_calls=0. Completes all feedback #3 items. Validated live.
